A major new report issued by the National Research Council of the National Academies on January 12 concludes that global warming is "'undoubtedly real,' and that surface temperatures in the past two decades have risen at a rate substantially greater than average for the past 100 years." In particular, the report examines the apparent conflict between surface temperature and upper-air temperature....

The IPCC was established in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP) to assess the available scientific, technical, and socio-economic information in the field of climate change. The IPCC site's offerings include special reports, technical papers, press releases, and information on its three Working Groups. Group III is investigating...

University of Massachusetts geoscientists Drs. Michael Mann and Raymond Bradley published this news-breaking research paper in the April 23rd, 1998 issue of Nature. The authors examine climate data in detail and conclude that three recent years were the warmest since 1400 AD. In addition to the paper (Adobe Acrobat [.pdf] format--click on "Study"), the site contains a news release, two of the...

The Pew Center for Global Climate Change has posted this report entitled "The Science of Climate Change: Global and US Perspectives," by Tom Wigley of the National Center For Atmospheric Research. The report discusses historical climate patterns, current climate changes, and predictions for the future (including the ability to detect significant changes). Introductory sections of the report may be...

The US Global Change Research Program (USGCRP) published this new bimonthly newsletter. Acclimations was created to inform and update citizens about research stemming from the US National Assessment of the Potential Consequences of Climate Variability and Change. Topics in the premier issue highlight key points from the Atlantic Coastal/Caribbean Workshop, as well as from the Southwest,...

For four days last week, the daily temperatures outside the Internet Scout Project office here in Wisconsin soared above 60 F (and on one day, above 75 F), and the lakes that surround Madison melted in one fell swoop, bringing winter to a lurching halt and restless thoughts of summer to the forefront. While such local temperature anomalies are not surprising (nor did other cities experience the...

Released on August 30 2000, this 34-page report from the World Wildlife Fund (WWF) warns that "global warming could fundamentally alter one third of plant and animal habitats by the end of this century, and cause the eventual extinction of certain plant and animal species." According to the report, the danger is greatest in the northern latitudes of Canada, Russia, and Scandinavia, where warming...

The NOAA Paleoclimatology Program posts data sets from recently published research articles. This data set is from an article by F.E. Urban et al., published in the October 26, 2000 issue of Nature [v.407, pp. 989-993]. Included here are the abstract, four figures (color), and links to the "del 18O data" and data description.

On January 22, 2001, the Intergovernmental Panel on Climate Change (IPCC) issued perhaps the most comprehensive and dire report to date on global warming and climate change. Over three years in the making, the full report includes contributions from 123 lead authors and runs over 1,000 pages. The report finds that global temperatures could rise as much as 10.5 degrees over the next century and...

Created by a host of organizations (Environmental Defense Fund, Natural Resources Defense Council, Sierra Club, Union of Concerned Scientists, US Public Interest Research Group, World Resources Institute, and World Wildlife Fund), this site seeks to provide evidence of the "fingerprints" and "harbingers" of global warming. A clickable map of the world enables users to take a closer look at...
